Fig. 5 — Conversion of timing deviations in received pulses and in timing 

 wave into timing deviations in regenerated pulses, for pulse shapes and timing 

 waves shown in Fig. 3. Timing deviations in regenerated pulses in relation to 

 timing deviation tp in pulses and ir in retiming wave is -pttp -\- ritr .

^B Correlated Amplitude and Time Deviations 



The amplitude and time deviations in the pulses are generally uncor- 



related, but this does not always apply to the timing wave. In particular, 



if a deviation Tr in the timing wave is the result of a change in the phase 



ip, it will be accompanied by a given amplitude variation. A change in 



I phase by A^ is related to the corresponding time deviation Tr by
